Summary ntawm Tshiab Zog Tsav Tsav Hauv Tswj Kev Lag Luam
Nyob rau hauv kev txhawb nqa ntawm lub xeev txoj cai ntawm kev txhawb nqa kev tsim kho cov tsheb tshiab, tag nrho lub zog tshiab tsheb kev lag luam tau pom tias muaj kev sib txig sib luag. Raws li qhov loj tshaj plaws kev lag luam rau cov tsheb tshiab, Cov tuam txhab suav yuav cia siab rau cov tsheb tshiab rau thawj lub sijhawm los sawv ntawm tib lub sijhawm pib nrog cov tuam txhab txawv teb chaws, thiab tsav tsheb tswj kev siv tshuab, uas yog ib qho tseem ceeb ntawm kev tsim tsheb tshiab, lub neej yav tom ntej ntawm kev tsim tsheb tshiab. Qhov dav thiab qhov dav ntawm nws qhov tseem ceeb yog qhov tseeb.
Ua ntej tshaj plaws, tus tswj lub cav yuav ua rau lub tshuab dav dav siv, nrog cov zis ntau zog thiab tsawg dua lub suab nrov. Lub hauv paus ntsiab lus yog los tswj lub tshuab kom ua hauj lwm raws li cov kev taw qhia, kev kub ceev, lub kaum ntse ntse, lub sijhawm teb, thiab lwm yam los ntawm kev ua haujlwm ntawm lub koomhaum kev khiav haujlwm. Cov nqi them rau txog 9.5% ntawm cov tsheb tshiab, uas yog ob zaug uas tsav tsheb.
Lub cev muaj zog xws li lub tshuab hluav taws xob txuas rau kev sib txuas roj thiab lub zog nyob hauv cov tsheb tshiab. Qhov tseem ceeb yog qhov tseeb. Nws tuaj yeem hais tau tias nws yog qhov tseem ceeb ntawm kev tsav tsheb thiab tswj kev ua haujlwm. Nws qhov tseem ceeb ntawm kev lag luam muaj xws li cov hluav taws xob cov khoom siv hluav taws xob thiab cov kev tswj ntawm kev tsav tsheb.
Raws li cov tub ntxhais tivthaiv ntawm lub tshuab fais fab, lub hwj huam ntaus nyiaj rau feem ntau ntawm tag nrho cov neeg tswj xyuas, thaum lub high-frequency, full-control type yog txoj kev loj hlob ntawm cov hluav taws xob cov khoom siv hluav taws xob.
Tam sim no, cov khoom siv hluav taws xob hluav taws xob feem ntau yog siv cov IGBT modules, uas yog cov khoom nruab nrab ntawm cov IGBT (IEPT) (Flammable Bipolar transistor chip) thiab FWD (freewheeling diode chip) los ntawm ib tus choj hluavtaws. Raws li tau pom los ntawm cov saum toj no daim duab, European thiab American tuam txhab thiab Japanese tuam txhab, nrog cov khoom zoo thiab ua technology, nyob hauv txoj hauj lwm meej hauv IGBT kev ua lag luam thiab tseem yog lub ntsiab lag luam ntawm Tuam Tshoj IGBT kev ua lag luam.
Txawm li cas los, nrog lub stimulation ntawm lub lag luam thiab kev pab ntawm lub teb chaws cov kev cai, ib tug xov tooj ntawm IGBT tuam txhab uas muag tau sawv nyob rau hauv Tuam Tshoj thiab tau ua tiav cov ntsiab lus. Piv txwv li, CRRC Times Fais tau Dynex nrog 50 xyoo ntawm cov cuab yeej hluav taws xob R & D keeb kwm; BAIC Tshiab Zog thiab CRRC tus Era Electric kos npe rau kev sib koom tes nrog kev pom zoo hauv Zhuzhou; Shenzhen BYD thiab Shanghai Advanced Semiconductor Manufacturing Co., Ltd. kos npe rau ib qho tseem ceeb Alliance Agreement, peb yuav tsim ib IGBT domestic saw saw. Nws tuaj yeem pom tau tias lub zos ntawm IGBT yog ib txoj kev loj nyob rau yav tom ntej.
Ua ib feem ntawm kev tsav tsheb, tus tswj lub cev yuav tsiv mus rau kev ua tau zoo thiab qis dua rau yav tom ntej. Tsis tas li ntawd, nrog rau cov chaw ntawm lub ntiaj teb tshiab lub zog tsav tsheb, kev siv hluav taws xob kev lag luam rau cov tsheb tshiab tau nce. Raws li kev twv txiaj, lub ntiaj teb lub cev muaj zog tswj tau mus txog 8 billion USD.
Lub cev muaj zog thiab hluav taws xob muaj kev sib koom tes yog txoj kev tsim kho
Peb pom tau tias los ntawm kev xav ntawm cov hluav taws xob tiv thaiv pob, feem ntau ntawm cov khoom siv hluav taws xob hauv OEM zoo ib yam li cov neeg tsav tsheb. Qhov no yog vim hais tias lub tshuab lub cev thiab cov hluav taws xob tivthaiv yuav tsum muaj kev sib raug zoo. Yog li ntawd, kev koom ua ke ntawm lub cev hluav taws xob tswj yog ib qho kev tsis pom zoo ntawm cov tsheb tshiab.
